CNET on Mac - page not found

Question

I've been having this problem for some time now - first I thought it was some temporary thing with CNET servers, but it doesn't seem so.

I can see the index pages of CNET sites (download.cnet.com, news.cnet.com), but when I delve deeper by clicking some application link on download.cnet.com or get direct link to some news from Twitter, I get error 'page not found' as seen on the image:

It seems that all links that point to CNET URLs having .html in them yield errors constantly. Other pages (e.g Mac software etc) are mostly OK (at least for the first click, but repeatedly refreshing gets me few random errors too)

This happens with all my browsers (Safari, Chrome, Firefox, Opera), whereas it does not happen with IE 8 running on Win 7 inside a VirtualBox on the same Mac, so it is not related to my network, but with my Mac borwsers somehow or Mac OS X.

BTW, all other websites are totally OK and this is only related to *.cnet.com sites. I have extensions and add-ons in Safari, Chrome and Firefox, but Opera is vanilla as I only use it for testing purposes, so could not be caused by some extension.

Specs:

• Mac OS X 10.6.7
• MacBook Pro 6,2
• Safari 5.0.5
• Chrome 11.0
• Firefox 4.0.1
• Opera 11.10
